摘要：

针对工业园区的污水排放企业种类较多、进水水量水质波动较大、污染物复杂且可生化性差、排放标准高的特征, 以浙江省德清县某工业园区实际污水处理工程为对象, 分析了水解酸化+A2/O+AO+芬顿氧化工艺处理以印染、食品制造、金属加工企业为主的废水排放的技术经济可行性. 实践结果显示, 出水水质的COD、NH3-N、TN及TP能稳定达到《城镇污水处理厂主要染物排放标准》 (DB33/2169—2018) 中的限值, 其余指标达到《城镇污水处理厂染物排放标准》 (GB18918—2002) 的一级A标准; 工程投资金额为8200元/m3, 实际直接运行成本为2.39元/m3.

Abstract:

Industrial park wastewater is characterized by various components, changeable water quality, complex pollutant factors, poor biodegradability, and high emission standards. A full-scale industrial park wastewater treatment plant in Deqing was used as an example to investigate the technical-economic feasibility of a process combining hydrolysis acidification, anaerobic-anoxic-oxic-anoxic-oxic (A2/O+AO), and Fenton oxidation in treating wastewater from various enterprises, primarily printing and dyeing, food manufacturing, and metal processing factories. The effluent chemical oxygen demand, ammoniacal nitrogen, total nitrogen, and total phosphorus stably met the required discharge limits for Urban Sewage Treatment Plants (DB33/2169—2018), while other indicators reached Grade A standard for Urban Sewage Treatment Plants (GB18918—2002). The engineering investment and actual operation costs of the wastewater treatment plant were 8200 and 2.39 yuan/m3, respectively.

Key words: industrial park wastewater, hydrolytic acidification, anaerobic-anoxic-oxic-anoxic-oxic (A2/O+AO), Fenton oxidation
